FLOAT FOE STEAIE TRAPS AND TEE LTKE.

Application filed October 5, 1921. Serial No. 505,524.

To all whom it may concern:

Be it known that 1, JOHN ROWLAND BROWN, a citizen of the United States,and a resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented anew and useful Improvement in Floats for Steam Traps and thelike, of which the,

following is a specification, the principle of the invention beingherein explained, and the best mode in which I have contemplatedapplying that principle so as to distinguish it from other inventions.

The present improvements relate more particularly to floats composed ofan internal hollow foundation and an external seamless metallic shell orcoating formed by electroplating such foundation. The latter may beformed of various materials as for example papier mach, celluloid andthe like, and the coating will usually be of copper although nickel orother metals that are capable of being electro-deposited may of coursebe used. Still more particularly the present invention relates to theconstruction and manner of attachment of a spud to such float wherebythe latter may be connected with suitable operating mechanism, such spudincluding either an internally or an externally threaded nipple.

To the accomplishment of the foregoing and related ends, said invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, and the annexed drawing disclosing but one ofvarious mechanical forms in which the principle of the invention may beutilized.

In said annexed drawing Figs. 1, 2 and 3 are corresponding axialsections of the nipple, a plate for holding the same, and the hollowfoundation or core of the float, shown in separate, i. e.. disassembledcondition; Fig. I} is a similar view of the foregoing parts in assembledcondition; Fig. 5 is a horizontal section through such nipple and platein assembled condition, the plane of the section being indicated by theline 55, Fig. it; Fig. 6 is a bottom plan view of the nipple and holdingplate; and Fig. 7 illustrates the adaptation of the device threadednipple.

The core 1, while shown in Figs. 3 and t as of approxhnately sphericalform, may of course take on any shape required by the for use with anexternally exigencies of the use to which the completed" float is to beput. It is also a matter of indifference, so far as the presentinvention device of present interest is tote attached, such device beingordinarily termed a' spud in the trade. At this point the'core or shell1 is formed with acircular aper ture 2 and surrounding such aperture thematerial is depressed to form an annular recess?) of the proper size andshape to receive a stamped-up metal plate 4. The latter is formed with acentral hollow boss or depression 5 preferably of polygonal crosssection and is adapted to receivea nip ple 6 that is formed with a head7 of corresponding cross section. The depth of the recess in boss 5 isslightly greater than that of such head so that when the nipple isinserted the boss may be criinped inwardly at its base, as clearly shownin Fig. 4, and tliereby firmly secure the nipple 6 to the p ate.

Such nipple is shown as internally threaded but may obviously take theform of an externally threaded stud or any other form of connectingelement may be utilized so long as it is provided with a suitable headadapted to be secured in the plate in the manner just described.Preferably for convenience in manufacture an internally threaded nipplewill be employed as a standard fitting and where an externally threadedstud-connection 8 is desired, the latter will simply be threaded intosuch nipple 6, as shown in Fig. 7.

It will be observed that the plate 4- is imperforate and that the depthof recess 8 surrounding aperture 2 in the core corresponds with thethickness of the flanged portion of such plate. Accordingly when thelatter is seated in the recess and there secured by a suitable cement,not only is the core completely closed, but the exterior surface thereofis left smooth and continuous insuring an even deposit of the metalliccoating, when the latter is electrolytically applied, right up to thenipple 6 or equivalent con necting member. lVhether the joint betweenthe latter and the plate 4: is perfectly sealed is a matter ofindifference since the plate in itself affords a perfect closure for thecore. The deposited metallic coating on the core being integrally unitedwith the plate supplements the cement between the latter and thedepression 3 and insures a very substantial and permanent mounting forthe spud as a whole.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1. In a device of the character described, the combination ofa hollow core having an aperture, a depression being formed in the wallof said core surrounding such aperture, a plate fitted in suchdepression and formed with an inwardly directed hollow boss received insuch aperture, and a member providing external connecting means for saidcore secured in such boss.

2. In a device of the character described, the combination of a hollowcore having an aperture, a depression being formed in the wall of saidcore surrounding such aperture, a plate fitted in such depression andformed with an inwardly directed hollow boss received in such aperture,and a threaded nipple providing external connecting means for said core,said nipple being formed with a head received in such boss and thelatter being crimped inwardly at its base, whereby said nipple is firmlysecured thereto.
